Domino’s, which has 1,054 stores in the UK but also operates in Ireland, Switzerland and Germany, said group system sales in the 13 weeks to April 1 rose to 311.1 million pounds ($433.6 million).

The London listed company, a master franchisee of U.S. group Domino’s Pizza Inc, said it opened nine UK stores in the period and remained on track to open 65-75 new stores in 2018.

Dominos said 541 out of its 1,054 stores in the UK had GPS tracker functionality, allowing customers to track their deliveries.

Much like its parent company, Domino’s Group is also focusing on sales through online channels to fend off competition from the likes of Just Eat, online food delivery company, which has sprung to the blue chip index in less than four year since listing.
